TYPE-BAR MACHINE.

SPECIFICATION forming pari', Of Letters Patent NO. 657,043, dated August 28, 1900. Application tiled August 14, 1899. Serial No. 727,151. (No model.)

To @ZZ whom, t may concern:

Be it known that I, ROSWEL'L II. ST. JOHN, a citizen ofthe United States, residing at Cleveland, inthe county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Type-Bar Machines; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to mechanism for feeding the blanks to a type-bar machine, constructed and operating after the manner peculiar to my invention, in which are employed a blank of any suitable hard material constituting the body of the finished bar and a strip of comparatively-soft flowing metal or composition in which the characters are formed at the same time as the said strip is temporarily incorporated with and made to constitute a part of the type-bar proper. The other parts of the machine are made the subjects of contemporaneous applications, serially numbered, respectively, 718,085 and 727,150; and this invention consists in the feed mechanism for both sets of blanks or parts of the complete bar, substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis a longitudinal sectional elevation of the said mechanism on line 1 1, Fig. 3; and Fig. 2 is a View on the same line with the mechanism in a different working relation, as hereinafter fully described. Fig. 3 is a plan view of the said mechanism, partly in horizontal section, on line 3 3, Fig. at. Fig. et is a side elevation of the part of said mechanism more particularly relating to the release of the soft edge strips. Fig. 5 shows the two blanks of the type-bar separate, and Fig. 6 shows them united and imprinted.

In Figs 1 and 2, A represents what may be considered a section of the machine-frame, in which there is a chamber or space wherein matrices B are assembled in number to constitute a line of printed matter. A transverse slot b opens to this matrix-chamber opposite the characters on the matrix, and the two blanks 2 and 4, constituting the hard body and the relatively-soft edge strip, re'- spectively, are conveyed to this slot in succession, substantially as shown, with the strip i always in advance of the body of the blank. On the front edge of the body 2 is a tongue 3, onto which the strip 4 is pressed in thc process of manufacture and as is now well known in this art.

Referring to Fig. 1, a pair of blanks 2 and 4 is shown as down on a table a on a plane with the slot b and ready to be carried forward therein, and just behind them is the tongue c of the plungerhead C, which is driven by power, and a connecting-rod or pitman d from the power-shaft D. The head C and tongue c have a back-and-forth sliding operation and are of such strength and force in action as to drive the tongue 3 bodily and instantly into strip 4 and at the same time take a full and perfect impression from the line of assembled characters. This step in the operation is illustrated in Fig. 2, wherein the plunger has just reached the limit of its thrust and a finished type-bar has been made, at least so far as this part of the operation is concerned. In the meantime, also, each one of the blanks 2 and has been delivered on the back of tongue c, in position to be dropped in the front of slot l), as in Fig. 1, the instant said tongue is withdrawn to position, as in Fig. 1. Now, obviously, any mechanism that will bring the said parts 2 and 4 into this relation successivelyand certainly for manufacture and conversion, as contemplated, will suffice, and I may, of course, employ Various combinations of widely-different details and getthe desired result; but still there are certain elements represented in the means here shown which are deemed fundamental and which with the other parts make a complete and eminently practical structure, and upon j these I desire protection.

Each set of blanks is held in supply or quantity in its own chamber or magazine, the f blank 2 in the chamberF and the blanks/i in the chamber H. The latter chamber is well to the front, and the feed is by gravity onto the inclined plate h, from which the strip is dislodged by the slide h and carried past the spring-pressed detaining-nger h2, whence it drops to the table a, and as it is supposed to be square in cross-section it is immaterial f Il IOC-

which side it rests on or whether it beexactly straight across as it lies. Meantime the bodyblanks 2 feed also by gravity from their magazine into the chute of which the plate his the cover and the plate g the bottom, and they are fed along so as to drop one at a time and one after another, as needed, onto table a behind blauk 4 and approximately at the same time or always promptly within time in order to be in waiting when the plunger c is thrown into action. It will be understood that the plunger c stops temporarily while the matrices are exchanged and locked and is then thrown in.

block, nuts confining the block and spring.-

A bell-crank has its long arm 9 engaged with said block, and its short arm l0 is slotted and in engagement with a like short arm 11 of another bell-crank having a long arm 12 and a link 13 therefrom to the slide-bar 14 on the near side of the view. The shaft 15 extends through to the other side and there carries an arm 12, connected by a link'13 to a sliding bar 14a in the side of the blank-chute corresponding substantially to bar 14 on the near side. Afeedslide 15 works in the bottom of the chute to remove one blank at a time from the magazine F, Fig. 2, and the said slide is actuated by a cross piece or part 16, fixed to the slide and to the sliding bars 14 141", Working in a slot on each side of the chute. This occurs automatically every time a thrust is made by the plunger C, and as one blank 2 is thus used another is at the same time fed. forward for use, and so on indefinitely.

The feed mechanism for the strips 4is-an extension of the foregoing mechanism through slide-bar 14, another connection being made between it and bar 14a by the cross-piece 17 working in longitudinal slots in the chute, as does cross-piece 16 at the upper end. This latter mechanism comprises a short rock-shaft 20, having one arm 2l engaging a hook or projection 22 on bar 14, and another arm 23, connected by link 24'with a lever 25, pivoted between its ends and having the strip rest or support 26 pivotally attached to its lower end. Normally the ent-ire column or bank of strips in magazine H is supported by this rest, and they are released one at a time by withdrawing the rest and temporarily suspending thel column by pressing the block 27 in against the next to the lowest strip. This releases the lowest one and allows it to drop down onto' slide h', as seen in Fig. 2. The magazine H is slotted to admit both the rest 26 and the block 27, and the said block ispressedinward to engagement by a short arm n on the side lof lever 25 bearing against a spring-,pressed pin n', socketed in the upper portion of said block. These'several parts are'so constructed and arranged that the block 27 is not withdrawn before the rest 26 gets back into supporting position, and as soon as the slide h is withdrawn the liberated strip 4 drops down against finger h2, as seen in Fig. 1, ready to ltake the next step in the next forward movement of slide h'. This slide is actuated through connection with cross-piece 17, fixed to its upper end. The plate h projects forward sufficiently to lodge the strip 4 always in advance of the drop of the blank 2 on tableh.

Y What I claim as new, and desire to secure by Letters Patent, is
